Usage of rotational sensors on volcanoes

| Summary: | Typical volcano-seismic signals on volcanoes include LP events, VT events and tremor. These events are detected and listed in catalogs as well as located and interpreted in the context of the volcano. Normally seismometers are used for these tasks. However, besides the translational ground motion, these events also generate rotational ground motion. Within this presentation we will highlight how rotational sensors can be used in this context. Following a few huddle tests in the field, we have installed the sensors in volcanically active regions such as Mount Etna and several interesting sites in Iceland. As a community effort we also started the python package TwistPy, to which more codes will be added in the future. |
